Your Protocol
From first use to second nature.
First Use
Unbox, load, refrigerate.
Your vials drop in exactly as expected. The inserts hold them upright. The latch clicks shut. You put it in the fridge and the case becomes invisible.
- Vials seat without force
- Latch closes flush on first try
- Fits on a standard fridge shelf
Week 1
Pull, dose, close. Every time.
The case is part of the ritual now. You reach for it twice a week, the latch pops open in one motion, you draw, you close. The inside is always dark between uses.
- Light exposure: zero
- Latch opens and closes clean
- Vials stay upright through daily use
Month 1+
You stop thinking about storage.
That is the outcome. The case did its job so well that it disappeared from your mental stack. Your peptides are protected. Your protocol runs on schedule.
- Compound integrity maintained
- Zero storage-related incidents
- One fewer variable in your stack
Opaque PETG shell blocks 100% of visible-spectrum light. Completely dark inside, every time the latch closes.
Stable from -20°C to 60°C. Cycles between your fridge and room temp daily without warping, clouding, or cracking.
Every insert is sized for standard lab vials. Vials sit upright and still. Nothing rattles, nothing tips, nothing shifts.
Hard-shell, sealed, compact. Goes through airport security without issue. Travel the way your protocol demands.
Built after your order, not pulled from warehouse stock. No inventory degraded under lights. Every case is new.
Designed and fulfilled in the USA. Fast, trackable shipping. No international delays, no middlemen.
The Material
PETG. Not just any plastic.
Most storage solutions use HDPE or clear acrylic. STIDRA uses PETG. It is the only common filament that is simultaneously opaque, cold-stable, and food-contact safe. It does not yellow. It does not become brittle in the fridge. It does not flex at the lid joint and let light in.
- 100% opaque. Zero visible-spectrum light transmission
- Stable from -20°C to 60°C
- Food-contact safe. No BPA, no off-gassing
- Impact-resistant shell. Survives travel and daily carry
- Precision-printed. No injection-mold inconsistencies
What our customers say.
“Finally something that actually blocks light. Three other storage solutions and this is the only one where the inside is completely dark. The latch clicks shut and stays shut.”
“I travel with peptides weekly. TSA has never flagged this case. Survived checked baggage twice. My vials are always exactly where I left them. Worth every penny.”
“Pulled this from a -20°C freezer and it looked and felt exactly the same. No cloudiness, no brittleness. Solid product, ships fast.”
“16-week protocol, vials twice a week. Before STIDRA I used a zip bag. Night and day. The latch gives me confidence nothing shifts during storage.”
STIDRA cases are sized for standard laboratory vials: 3mL, 5mL, and 10mL. The Mini Case fits 3mL vials, the Standard fits 5mL, and the Pro fits 10mL.
PETG is food-contact safe and does not off-gas or leach chemicals at refrigeration temperatures. Your peptides never contact the plastic directly. Vials remain sealed in their original glass containers inside the case.
PETG is stable from -20°C to 60°C. It will not become brittle, crack, or warp through daily fridge-to-room-temperature cycles. Sub-zero freezer storage is handled without issue.
STIDRA cases are hard-shell, compact, and fully sealed. They go through security without issue. Always carry documentation for your compounds when traveling.
Every STIDRA case is printed to order in Miami, FL. Orders ship within 3-5 business days via USPS or UPS with tracking. Free shipping on all US orders. Expedited options available at checkout.
